A steady‐state apparatus for measuring thermal conductivity by a direct method, viz., water calorimetry, is described. The accuracy of measurement is about 1 to 3% in the temperature range 30° to 30O°C. and about 3 to 10% in the range 300° to 1200°C. The samples are rods 9 in. long and in. in diameter, although smaller sizes can be accommodated. One feature of the design is that the sample thermocouples can be plugged into the unit. Curves for samples of alumina, stainless steel, and graphite are included.
